JOHN S. FRAY, OF BRIDGEPORT, CONNECTICUT TOOL-HANDLE.

SPECIFICATION forming part of Letters Patent No. 282,712, dated August 7, 1883.

Application filed April To all whom it may concern:

Be it known that I, JOHN S. FRA'Y, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Oonnecticut, have invented certain new and usehereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked there- Figure 1 of the drawings is a perspective view of my invention, Fig. 2,-a sectional view on an enlarged scale, and Fig. 3 an end view of Fig. 1 with the tool removed; Fig. 4, adetail view in perspective of one of the gripping or holding jaws.

The present invention has relation to certain new and useful improvements in that class of tool-holders in which the shank of the tool is held between two movable jaws brought firmly against it by a screw-threaded sleeve.

The object of the invention is to improve the construction of the above class of toolholders, whereby the tool is more firmly held between the jaws with less liability of its pulling out or the jaws turning upon their axis, which ob jects I attain by the construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A rep resents a toolhand1e, preferably of that class formed hollow for containing the several tools, one of which is shown at a. To the lower end of the handle A is secureda socket, B, provided with a circular recess, and having screwthreads upon its exterior to receive ascrewthreaded sleeve, 0, provided with shoulder g, and having wings I), for convenience of turning it. The shanks of the gripping-jaws D are semicircular in form and extend into the socket their entirelengths, the jaws being provided with shoulders f, which abut against the lower edge of the socket. They are also each provided with perforations 0 at their upper 23, 1883. (No model.)

extremities, through which passes a pin, (Z, said pin also passing through the socket. As

above described, it will be seen that the pin not only passes through the shanks of the gripping-jaws to hold them parallel with each other, but also through the socket, thus preventing the jaws from turning by the employment of a very simple and effective means, without the necessity of springs, rectangularshaped cavities with ribs, and other similar devices. The jaws D are each formed upon their inner face with a recess, 6, which i11- creases in size at its inner end, as. shown in Fig. 4; or, in other words, a tapering recess increasing in size in a direction toward the inner end. The extremity of the shank of the tool a is in form to correspond to the form of the recess in the jaw. Thus when the jaws are brought together against the shank by the sleeve 0 it will be impossible for the tool to drop out or work loose.

Having now fully described my invention,

the shanks when the jaws are brought to gether to secure the tool, as shown and described.

- In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN S. EBAY.
